Distinct variety of Streptocarpus named Revolte

ABSTRACT

A new variety of Streptocarpus plant is characterized by its small, narrow and flattened leaves. The plant has bouquet-type flowers standing above the leaf line. The flowers have a flattened appearance due to the flat bottom petals and reflexed top petals.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Streptocarpus×hybridus known by the varietal name of Revolte. The new cultivar is the product of a selective breeding program and is a hybridization of English hybrids of which the standard was a Streptocarpus known by the varietal name Kolibri. The new cultivar differs from the English hybrids in respect of color, early flowering, plant form and growth characteristics.

The new cultivar is generally characterized by its small, narrow and flattened leaves. The plant has bouquet-type flowers standing above the leaf line. The flowers have a flattened appearance resulting from flat bottom petals and reflexed top petals.

The new cultivar was discovered in 1979 in Reiskirchen, Federal Republic of Germany; was first asexually reproduced by cuttings in Reiskirchen, Federal Republic of Germany; and has been repeatedly asexually reproduced by cuttings at Oglevee Floral Company in Connelsville, Pa. It has been found to retain its distinctive characteristics through successive propagations.

The new cultivar, when grown in a greenhouse in Connellsville, Pa., has a response time of eight weeks from a well-rooted young plant in a 21/4 inch pot to a flowering plant in a 6 inch pot.

DESCRIPTION OF THE DRAWING

The accompanying drawing illustrates the new cultivar, the color being as nearly true as possible with color illustrations of this type.

DESCRIPTION OF THE NEW PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which define these characteristics were collected from asexual reproductions carried out by the Oglevee Floral Company in Connellsville, Pa. The plant history was taken on eight week plants blossomed under natural light in a greenhouse and color readings were taken indoors under 100 foot candles of cool white fluorescent light. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London unless noted differently.
